just use the red line and be done with it. its as accurate as any and more so, as using the ghost ball works for a beginner but you also have to estimate its size when mentally placing it there so that adds in mistakes.

I was expecting to see something that might be fake (I guess it still could be) but their reactions make it look pretty darn legit.

I don't know what the probability is of getting a crazy lucky roll, but those tables look like Heyball tables, which makes a roll like any of those much less likely than on an American pool barbox with bucket pockets. If you assume the chance for a super lucky roll like any one of those is, I don't know, 5%? Which is 1/20. Then it's (1/20)^4 = 1/160,000. If it's 1% (probably a tad low), then it's (1/100)^4 = 1/100,000,000 (one in one hundred million). If it's somehow as high as 10%, which I doubt, then it's (1//10)^4 = 1/10,000.

So somewhere between 1/10,000 and 1/100,000,000 with most likely between 1/160,000 and say 1/5,000,000. Unless it's a banger playing me, in which case it's no worse than 50/50.

Was a fun watch regardless.

Ghost ball trick: It's the exact size as the object ball and always frozen to it. You can train your eyes by freezing the CB to another ball and walking around it till you memorize the look or you can no longer miss.

Also this might work:
A right triangle half the height of the object ball.


Here's an interesting artifact of Jimmy Reid's Equal Angle Opposites:



The Yellow line shows the intended object ball line.
The Red line is contact line. You can use your stick on close shots to get the hang of it.
The Black line is the shot line running parallel to the Red contact line.
Notice, the Black shot line intersects the Yellow shot line at the base of the mythical Ghost Ball.
The blue line is just the line of centers.
The half ball hit is incidental. Could be any pool shot angle; different angles and parallelogram but the connection points would be the same.
